• A. Time signature
• B. Tonality
• C. Modulation
• D. Unison

Answer: (B)

Tonality is the arrangement of pitches and chords of a musical work in a hierarchy of perceived relations, stabilities, attractions, and directionality. In tonal music, a central pitch or key center—the tonic—anchors the piece. The surrounding pitches and chords have functional roles that feel more or less stable: the tonic feels settled, while chords like the dominant create tension that pushes the music forward toward resolution back to the tonic. This setup gives listeners a sense of direction and a predictable pull, so you hear a musical arc as it moves through harmony. Time signature is about how beats are organized in measures, not about pitch relationships. Modulation is the act of shifting from one key to another, which is a movement within tonality but not its defining structure. Unison refers to voices sounding the same pitch, which is about pitch equality rather than how pitches and chords relate hierarchically.
